Hi,

This is an example of an entry in the log, left by HttpLimitReqModule:

2013/10/27 10:00:11 [error] 1402#0: *313355 limiting requests, excess: 0.580 by zone "zone1", client: 20.147.43.103, server: api.acme.com, request: "GET /location/locate-ip?key=xxxx&ip=85.210.42.204 HTTP/1.1", host: "api.acme.com"

What does "excess: 0.580" mean exactly? What is the unit of that value? Requests? Requests per second?
There is no information in the documentation, as far as I know.

Thanks in advance,

Brian
